十分感谢大家的帮助,已经弄清楚了,确实是单波功率.红色的也是收光单波功率.要是发光的不太可能,单波功率一般不大于5DB,否则产生非线性效应今天给我一个表,叫我计算收发光功率,请问这是什么意思呀?红字是单波发光功率吗?绿的是单波收光功率?<table cellspacing="0" cellpadding="0" width="745" border="0" style="WIDTH: 559pt; BORDER-COLLAPSE: collapse;"><colgroup><col span="2" width="72" style="WIDTH: 54pt;"></col><col></col><col width="97" style="WIDTH: 73pt; mso-width-source: userset; mso-width-alt: 3104;"></col><col></col><col span="7" width="72" style="WIDTH: 54pt;"></col><col></col></colgroup><tbody><tr height="19" style="HEIGHT: 14.25pt;"><td width="72" height="19" style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 54pt; BORDER-BOTTOM: #ece9d8; HEIGHT: 14.25pt; BACKGROUND-COLOR: transparent;">Channel</td><td width="72" style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 54pt; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent;"> WL (nm)</td><td class="xl24" width="97" style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 73pt; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent;">
